MEMS Seminar: Acoustic Nanofluidics

Apr 14

Friday, April 14, 2017

12:00 pm - 1:00 pm
Fitzpatrick Center Schiciano Auditorium Side A

Presenter

Professor James Friend

Acoustic waves have found new utility in microfluidics, providing an enormously powerful ability to manipulate fluids and suspended particles in open and closed fluid systems. In this talk, we cover some fundamental and powerful concepts of acoustic wave generation and propagation often overlooked in the literature, and follow it with exploration of new phenomena observed at the nanoscale. In fact, the usefulness of acoustic waves at the micro-scale is even more compelling at the nano-scale, in ways not predicted by classical theory. Particle deagglomeration, fluid pumping, pattern formation, and other curious physical phenomena will be shown in the context of potentially useful applications. Along the way, the fascinating underlying physics tying together the acoustics, fluid dynamics, and free fluid interface in these systems will be described.Lunch will be served from 11:30 am - 12:00 noon.
